J-Lo promised that it was "going to be one of the most historic tours ever," admitting that she didn't think "there has ever been something where these Latinos have come together like this as family."

But what she didn't realize was that every family has drama. And for the 42-year-old former American Idol judge, it plays out in the pages of the Hollywood Reporter.

According to that website, Wisin y Yandel have dropped out of the tour just 12 days before it starts in Montreal.

In a joint statement, the Puerto Rican reggaetoneros wished "Jennifer and Enrique, as well as the tour, the very best," and are promising "to do [their] best to announce an upcoming U.S. tour in the very near future."

Randy Phillips, president of AEG Live, the tour's promoter, tells the Hollywood Reporter that a "host of things" went into the decision. But ultimately, the departure was "amicable."

"It was better for their careers to do their own tour than to be a third act on this tour," he says. "There were timing issues, how long the show could be and just a myriad of issues."

According to Philips, "an artist that caters to a Latin audience" will fill Wisin y Yandel's spot, though that announcement won't be made until next week.
